Sandboxie Support

With all this Firefox sandbox level upheaval/confusion, I have been wondering about the following: 1) Could using Sandboxie together with a recent Firefox 59 (=FFX sandbox level 4) theoretically make things LESS secure ? In other words, could Sandboxie conflict with the Firefox sandbox, potentially ...

I am pretty sure that any downloaded file will NEVER contain any ADS info by itself. In other words, Alternate Data Streams cannot be transferred over the Internet when downloading a file. They can only "live" within NTFS file systems. https://superuser.com/questions/147922/does-moving-a-file-outsid...

For each downloaded file, Windows adds some zone information in an NTFS alternate data stream (ADS) . This "Zone.Identifier" information is used for showing warnings about running files downloaded from the Internet and is also used by Windows Smart Screen to trigger a check of the reputation of down...

Confirmed fixed, E10S working great (FFX 52 x64, Win 10 x64).

A BIG THANK YOU to the devs, you guys are ... great

All the best,

Hi again, Will setting the security.sandbox to 0 and browser.tabs.remote.autostart.2 to FALSE seriously impact the security of firefox if I run it OUTSIDE of sandboxie? I'm asking the question, cause I use firefox a lot exactly in that way and I wouldn't want to change settings permanently if it me...

I noticed that "\Device\Mup\" is no longer added automatically.

Am I missing something, or is "\Device\Mup\" obsolete and thus no longer necessary ?

Thanks,
Spaceman Spiff

Update: Changing the security.sandbox to 0 in about:config fixed it! Thanks for pointing me in the right direction! Disabling the multiprocess mode by changing both " browser.tabs.remote.autostart " and " browser.tabs.remote.autostart.2 " to FALSE also fixes the problem. So it seems to be related t...

Same here. Blank pages with FFX 51.0 and e10s/multiprocess enabled. Disabling multiprocess fixes the rendering issues. In my humble opinion, working on support for multiprocess and content-sandboxed ("Sandbox level"=1 and above) Firefox should be top priority now. Multiprocess isn't going away (on t...

I can confirm this exact issue (same error code as in scootz99's screenshot).

Config: SBIE 5.16, FFX 50.1 (64 Bit, multiprocess enabled), Windows 10 (64 Bit).

Just an update after doing more research: I have disabled the untrusted font system mitigation for now. Consequently, all web fonts are displayed properly now. So this update is not about the original issue. But there seem to be general font rendering issues when FFX 50 is run sandboxed. Even though...

First of all, let me thank you again for your effort and patience :P Spaceman Spiff, Forcing a program, or using right-click --> Run Sandboxed should not trigger different behaviors. Do you have any modifications made to your .ini file? Yeah, I figured that it should not make a difference. However, ...

What I meant was if the issue also happens while not-sandboxed. I tested this with both FF 32 bits and 64bits and the behavior is the same, it doesn't matter whether Firefoxt is sandboxed or not, if Untrusted Fonts policy is enabled, some icons/fonts do not load. I just wanted to confirm this behav...

After some testing, what we are seeing is that once Untrusted Fonts is Enabled, both Host and SBIE Firefox will stop displaying the fonts. It does not seem to be happening for Sandboxie only. Hmm, sorry if I sound ignorant, but could you please elaborate what you mean by that ? What do you mean by ...

Alright, to clarify... When you select Untrusted Fonts, Firefox does not display certain fonts when Sandboxed [but it works fine outside of it]. Is this correct? Exactly :mrgreen: I have enabled "Untrusted Fonts Blocking", but I am still unable to repro the issue on Win 10 Pro x64. If you could pro...

First of all, thanks for the quick reply. I just updated to SBIE 5.15.4 (so that we are on the same page). No change. Just to be clear: Have you enabled the above mentioned Win 10 "Block Untrusted Fonts" mitigation? (In can be enabled in the Group Policy Editor [Computer Config --> Admin. Templates ...
